What if the OP goes to a Cosworth Intake plenum... will he see similiar results on a non-revup as what they posted on their site?

 

The dynograph on cosworth's USA website indicates that there is practically no gains in the stock rpm range. The only difference you'll see with the cosworth is at past redline (so you'll need a flash to push it out), the cosworth allows the VQ to be able to continue making power to the low 7000s. I have one that is replacing my spacer + MREV2 and I'm expecting to lose 5-10whp, through the stock revband.

 

My mods

5/16" spacer
Z-tube with K&N drop in
Test pipes
Fast Intentions true dual


What would be the best to tune with and what gains would I see from just having it tuned? roughly? On a non rev-up. Sorry for thread jacking...just assumed your questions have been answered.
